ENGLISH ABSTRACT: There is a relative lack of information in sport psychology research literature about the role of psychological dimensions in team sport – especially in soccer (Reilly et al., 2000). It is consequently not surprising that research on applied strategies in soccer has concentrated mainly on technical, tactical and physiological aspects. This defies anecdotal evidence and literature reports alluding to the importance of psychological and team factors in achieving sport excellence.
This study examined the role of mental toughness, psychological skills and team cohesion in soccer performance. It also considered differences between individuals from different playing positions regarding these modalities.
A total of 263 male soccer players aged between 17 and 32 years from 16 South African tertiary institutions participated in the study. A cross-sectional study design was used to determine the players’ mental toughness, psychological skills and team cohesion by means of the Sports Mental Toughness Questionnaire (SMTQ); the Athletic Coping Skills Inventory-28 (ACSI-28); and the Group Environmental Questionnaire (GEQ). The final log standings at the 2012 University Sport South Africa (USSA) Soccer Championship were used as an indication of team performance.
The results yielded differences between successful and less successful teams with regard to age, previous tournament experience, and the time players had been part of their respective teams.
There were no significant differences between the teams for any of the mental toughness and psychological skills scores. However, group cohesion did play a role in team performance. The more successful teams scored better than their less successful counterparts in the following subscales of the GEQ: Individual attraction to group-social and individual attraction to group-task. However, the less successful teams scored better than their more successful counterparts regarding group integration-task, and group integration-social.
Practical significant differences of moderate magnitude were observed for five of the 96 player positional comparisons. Midfielders scored higher than the defenders and forwards on the control subscale of the SMTQ. The forwards recorded higher scores than midfielders with regard to the GEQ subscale of group integration-task, whereas goalkeepers yielded higher scores than midfielders on the group integration-task subscale. There was a difference between the scores on the constancy subscale of the SMTQ where the defenders outscored the midfielders. No positional differences were recorded for any of the psychological skills.
The overall results revealed that at the developmental level of the study sample, team cohesion and other moderating variables might be the key to enhanced performance of soccer teams. In addition, the results supported the general assumption that a relationship exists between playing positions in team sports and various psychological variables.
